SPECIFICATION forming part oi' Letters Patent No. 385,828, dated July l0, 1888.

Application led April 4, i888. Serial No. 269,590. (No model.)

To @ZZ wwm it may concern.-

Beit known that l, WILLIAM H. H. Stann- LTN, a citizen ofthe United States, residing at South Fork, in the county of Howell and State of Missouri, have invented a new and useful Improvement in Ohurns, of which the following is a specification.

The invention relates to improvements in churns having reciprocating flashers; and it consists in the construction and novel combination of parts, hereinafter described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure lis a perspective View of a churn embodying the invention. Fig. 2 is a central vertical longitudinal section.

lteferring to the drawings by letter, A designates the main frame of the machine, composed of the base-board a, the standards, the lower side rails, a a', the upper side rails, a2 a, and the upper end rail, a3, at the end of the frame opposite that on which the churn-barrel is seated.

B is a transverse shaft journaled in bearings b b, secured to the upper side rails, a, a short distance from the end rail, a3, and carrying the large pulley b. One journal of said shaft is extended and squared l'or the attachment of the crank-handle b2, by means of which the machine is actuated.

O is a transverse shaft journaled in bearings c c, secured t0 the lower side rails adjacent to the churn-barrel and carrying the pulley c', smaller than thepulley b and connected therewith by the belt 0"'.

c3 is a crank on the shaft O, to which crank isjournaled the lower end of a pitman, d, pivoted at its upper end to a vibratory arm, D. One end of the arm D is pivoted between the arms ofa bifurcated standard, d', rising about centrally from the end rail, a3, and to the other end is loosely hung the flasher-rod e ofthe upper dasher, E, which is suspended within the cylindrical churn-barrel F.

G is a vibratory arm pivoted at one end between the arms of the standard al above the pivotal point ofthe arm D and having loosely hung to its other end the dasher-rod h of the lower dasher, H, similar to the dasher E, the said dasher-rod h passing through a suitable opening in the dasher E. The dashers E and H are respectively provided with the similar series of openings, e and h.

lis a transverse rock-shaft journaled in bearings z', secured to the lower side rails, a', at suitable opposite points, which shaft has extending from itin opposite directions the arms z" The arm t, which extends toward the churn-barrel, has its end connected with the arm D by a pivoted link-rod, J, and the arm i has its end connected with the arm G by the pivoted link-rod K.

L is a circular flanged s'eat on the outwardlyextended end of the base-board c, to receive and steady the lower end of the churn-barrel, and l is a lid or cover for said barrehprovided with openings for the passage of the dasherrods.

It is evident from the above that when the crank-handle is turned the crank-shaft O is rotated by means of the pulleys and belt and the arm D vibrated by means of the crank c3 and pitman d.

As the arms ofthe rock-shaft extend in opposite directions and are connected, respectivelynvith the arms D and G by the link-rods J and K, the motion of the former arm will be communicated to the latter in the reverse directiou, and the dashers suspended from the ends of said arms will alternately approach and recede from cach other, creating very strong and abruptly alternating up and down currents in the cream and causing the butter-globules to separate rapidly therefrom.

Having described my invention, I claimi. The combination of the horizontally-vibrating arms, the rockshaft arranged below said arms and having independent connectionl therewith, the crank-shaft arranged below the said arms and to one side ol' the rock-shaft, the link connecting the crank-shaft with one of said arms, and mechanism l'or rotating the crank-shalt, as set forth.

2. rlhe combination, in a churn, of the barrel, the dashers Fi H, having the rods e h, the oppositelyvibrating arms D G, the rock-shaft I, having the oppositely-extending arms i i2. the link-rod J, connecting the end of the arm i with the arm D, and the link-rod K, connecting the end of the arm ff with the arm G, substantially as specified.

8. Ina churn, the combination,with the bar- ICO rel, the similar upper and lower dashers E H, In testimony that clam the foregoing as my having the rods e h, the oppostely-vibrating own I have hereto affixed my signature in presarms D G, the rook-shaft provided with the ence of two Witnesses.
